The 2PM Intermediate Advisory set Kirk's winds at a possibly conservative 60 MPH. This cyclone is undergoing a healthy rate of deepening today, going from an estimated1004mb while the plane was approaching, to 998mb during the last pass though the center.
Microwave passes show clear evidence of an incipient eye, not yet apparent in conventional satellite.
The last pass though Kirk's center also supports potential for an eye to form today, with a very impressive warm core already in place.
